The main diameters of ice packs (ice bags) are divided into two types: the standard diameter is approximately 5 cm, the medium diameter is about 6 cm, and the large diameter is approximately 7 cm.
Ⅰ. Common diameters (inner diameter)
5 cm (small mouth): Older models / children's models, water filling is slow, and ice cubes are difficult to enter.
6 cm (medium mouth): The most commonly used, mainly for hospitals / home use.
7 cm (large mouth / wide mouth): Preferred for sports / medical use, ice can be added quickly and easy to clean.
II. Purchase Tips
For medical/sports applications, choose the 6cm wide mouth version as it fills ice quickly and is less likely to spill.
For household/children's use, opt for the 4.5cm standard mouth version, which is suitable for regular ice cubes and offers better leak prevention.
The mouth size is uniformly threaded and screw-cap type. The materials are mostly PP/PS, ensuring safety and durability.
